4、个人总结

首先是用时，快开学前的十几天开始写的，零零碎碎的总共大概花了40+h。勤快的时候一天七八个小时熬到半夜，懒得时候打开电脑发呆ing，总体还是挺满意的吧。
其次是项目完成度，由于临近开学，时间上比较匆忙，距离我最开始的设想，还“差移除图片、调整顺序、输出图的文件大小（或尺寸，或清晰度）选择 ”这三项没搞，不过搞起来也不是很难。

TODO List:

最后就是代码优化，UI部分写的一团乱麻。。以后的话，尽量还是分模块写，一小块一小块实现，最后再归一化，这样代码也比较清晰，不会显得太过臃肿。

ps：Swing是真的垃圾，被弃用不是没有原因的。再写UI的话，估计也会使用其他UI工具。
